Scope of the Manual
This Instruction Manual provides installation, startup
and maintenance procedures for the Type ACE95jr
tank blanketing valve. See Figure 1.
Product Description
The Type ACE95jr tank blanketing valve is an
extension of the Type ACE95 tank blanketing valve
and is intended to handle lesser ows on gas
blanketing systems. The valve prevents a stored
product from vaporizing into the atmosphere, reduces
product combustibility and prevents oxidation or
contamination of the product by reducing its exposure
to air. The Type ACE95jr maintains a slightly positive
pressure and thereby reduces the possibility of tank
wall collapse during pump out operations.

Principle of Operation
The Type ACE95jr tank blanketing valve controls the
vapor space pressure over a stored liquid. When liquid is
pumped out of the tank or vapors in the tank condense,
the pressure in the tank decreases. Tank pressure is
sensed by the large actuator diaphragm. When tank
pressure is less than the valve set pressure, spring force
moves the actuator diaphragm downward.
When the actuator moves downward, it pushes open the
valve plug which allows ow in to the tank (See Figure 2).
When pressure in the tank increases above the setpoint,
the large actuator diaphragm is pushed upward, allowing
the valve plug to close.
The valve plug is balanced (inlet pressure equal upward
and downward force on these components); therefore,
the outlet (control) pressure of the unit is not affected by
uctuating inlet pressure.
Installation
!
WARNING
Personal injury, equipment damage or
leakage due to escaping accumulated
gas or bursting of pressure-containing
parts may result if this gas blanketing
system is over pressured or installed
where service conditions could exceed
the limits given in the Specications
section and on the appropriate
nameplate or where conditions exceed
any ratings of the adjacent piping or
piping connections.
To avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices (as required by Title 49, Part 192,
of the U.S. Code of Federal Regulations,
by the National Fuel Gas Code Title 54

of the National Fire Codes of the National
Fire Protection Agency or by other
applicable codes) to prevent service
conditions from exceeding those limits.
Additionally, physical damage to the
tank blanketing system could result in
personal injury and property damage due
to escaping accumulated gas. To avoid
such injury and damage, install the tank
blanketing valve in a safe location.
This Type ACE95jr tank blanketing valve was
assembled and preset to the customer specied
pressure and setpoint. The control pressure range of
the valve is stamped on the nameplate fastened to the
upper actuator case. The gas blanketing setpoint is the
only adjustable feature on this unit.
1. Get a qualied personnel when installing, operating,
and maintaining valves. Before installing, inspect
the valve and tubing for any shipment damage or
foreign material that may have collected. Make
certain the body interior is clean and the pipelines
are free of foreign material. Apply pipe compound
only to the male pipe threads with a screwed
body or use suitable line gaskets and good bolting
practices with a anged body.
2. Inspect the nameplate on the upper actuator
case. It displays the model number, serial number,
a blanketing gas supply pressure range, the
maximum inlet pressure, set pressure and CV
value. These must agree with the system that you
are blanketing. The serial number will be needed in
any communication with your local Sales Ofce.
3. Clean the gas blanketing supply lines of all dirt
and foreign material before connecting them to the
Type ACE95jr tank blanketing valve.
4. The valve must be mounted so the actuator case is
horizontal, as shown in Figure 3. The valve should
be mounted above the tank. Three connections are
required: a) blanketing gas supply to valve, b) valve
outlet to tank and c) sensing line to tank.

Piping Considerations
Note
Piping lengths are best when they are
kept short with a minimum number of
elbows and ttings.
Inlet Piping
CAUTION
Undersized piping may inadequately
deliver blanketing gas at the
specied inlet pressure under full
ow conditions. This may result in
unacceptable performance under high
demand conditions.
The blanketing gas supply line should be equipped with
a Number 100 mesh strainer to remove dirt and pipe
scale. Inlet piping must be sized to adequately deliver
blanketing gas at the specied inlet pressure under full
ow conditions.
Outlet Piping
CAUTION
Unnecessarily long or restricted outlet
piping may result in poor setpoint control.
Valve outlet is piped into the tank vapor space. Outlet
piping must be full size and self-draining to the tank.
The valve should be situated above and as close as
possible to the tank vapor space for best performance.
Sensing Line
The sensing line should be 1/2 in. / 13 mm tubing or
pipe, must slope toward the tank and should not contain
low points (or traps) that could catch liquid. The sensing
line must enter the tank above the liquid level at a point
that senses the vapor space pressure and is free from
turbulence associated with tank nozzles or vents.
Note
Best control is obtained when both
connections to the tank are separate.
If the tank has only one available
nozzle, contact Emerson™. for alternate
methods of installation. A single array
manifold is available for such situations.
Gauges and Shuto Valves
Inlet gas shutoff valves are desirable for servicing.
If this Type ACE95jr tank blanketing valve was not
ordered with an inlet pressure gauge, it is advisable to
install a gauge between the inlet shutoff valve and the
blanketing valve.
Note
Safety considerations may dictate full
port shuto󰀨 valves between the tank and
blanketing valve and at the valve inlet.
Startup, Adjustment and Shutdown
Note
Tank vents and safety relief valves must
be in place and operating.
Startup
CAUTION
Always open the outlet valve before
the inlet valve. Operation in the reverse
order could result in inlet pressure being
applied to the actuator casing, potentially
damaging it.
1. Open shutoff valves between the blanketing valve
and the tank (both sensing and outlet). See Figure 3.
2. Slowly open the supply line shutoff valve (to the
blanketing valve) and leave it fully open.
3. Monitor the tank vapor space pressure.
Adjustment
The setpoint of this unit is factory set. Adjustments
should be made in small increments while the unit is
supplying gas to the tank. To change the setpoint:
1. Remove the actuator cap (key 1) from the top of
the spring case (key 7). See Figure 4.
2. Loosen the lock nut (key 3) and turn the adjusting
screw (key 2) clockwise to raise the setpoint.
(Turning the screw counter-clockwise lowers
the setpoint.)
3. Observe the effects of the change.
4. When the adjustment is complete, tighten the lock
nut (key 3) and replace the actuator cap (key 1).

Type ACE95JR

Shutdown
Installation arrangements vary, but in any installation
it is important to open and close valves slowly. When
shutting down the system, close the upstream supply
shutoff valve rst. Refer to Figure 3.
Maintenance
Valve parts are subject to normal wear and must
be inspected and replaced as necessary. The frequency
of inspection and replacement of parts depends on the
severity of service conditions and the requirements
of local, state and federal regulations. Due to the
care Emerson™ takes in meeting all manufacturing
requirements, use only replacement parts manufactured
or furnished by Emerson.
All O-rings, gaskets and seals should be lubricated with
a good grade of general purpose lubricant and installed
gently rather than forced into position. Approved
lubricant, sealants and adhesive are
as follows:

Disassembly and Assembly
CAUTION
Before removing the valve from the line,
ensure that it is isolated from the gas
supply pressure and that all pressure
has been released from the valve. (The
drain on the inlet lter is convenient
to bleed o󰀨 gas.) All tank connections
must be closed or sealed in accordance
with your plant’s operating and safety
procedures. If installed, electrical
connections to the explosion proof
switch must be deactivated before
opening the enclosure or disconnecting
the wiring (in accordance with codes
and safety practices).
It is recommended that all seals and diaphragms be
replaced as a matter of good practice whenever a
valve is disassembled and re-assembled. Parts kits
are available through your local Sales Ofce.
Note
When ordering parts, have your model
number, serial number and control
pressure range. Valve information is on
the nameplate (attached to the upper
actuator case).
When performing disassembly or re-assembly
operations, refer to Figure 6 for key numbers (unless
otherwise directed).
